Since its development in the first half of the 20th century, Nuclear magnetic resonance (NMR) spectroscopy is an integral tool across various scientific disciplines. The method’s relevance and power ...

Nuclear magnetic resonance (NMR) spectroscopy is a technique that detects the chemical environment of atomic nuclei by the absorption of radio-frequency electromagnetic radiation when in the presence ...

Nuclear magnetic resonance (NMR) spectroscopy was developed to detect protons, and has since then been applied in studying the molecular structure of proteins, RNA, DNA complexes, and interactions ...

In X-ray crystallography, X-rays of sufficient energy are used to excite the inner shell electrons in the atoms of a sample. The electrons move first to the outer orbitals and then down into the ...

The picture caption stating that “the Varian A-60, the console of which is shown here, was the first commercially available NMR spectrometer” is incorrect (C&EN, Sept. 9, page 70). Varian launched the ...

Determining alcohols using NMR spectroscopy is carried out in order to introduce students to NMR spectroscopy at an early stage in their undergraduate career. The experiment aims to enable students to ...

Nuclear Magnetic Resonance (NMR) was first experimentally observed in late 1945, nearly simultaneously by the research groups of Felix Bloch, at Stanford University and Edward Purcell at Harvard ...

The European Union put forward the REACH regulations in June 2007 for the registration, evaluation, authorization and restriction of chemicals. The aim of this resolution was to raise the levels of ...
